roman-MACHINE;

proved pullergs shown attached, is of the or-'--- dmary construction,and as shown in the drawings, is provided with two needles, 1, 1, whlchare carried by the needle bar 2 reciprocating in the head 3 supported onthe overhanging arm 4. The presser bar 5 carries a presser foot 6 at theusual lever 7 for lifting the same is of the machine. I have alsoprovided a lever 8 pivoted to the head of the machine, whichextends-underneath the stud 9 mounted on the presser bar 5,and saidlever 8 is operatively connected by asuitable'chain'or otherflexibleconnection 10, to a treadle or knee lever,

whereby the same may be lifted. The work support 11 is spaced from thebedpplate of Patented any 6, 119115;. Application filed June 15, 1907.Serial No. avaais.

srncmr. nmcnn'm the lower end, and

the machine 12 in the usual manner; The

feeding mechanism is the ordinary four -motion feed, and comprises afeed bar 13 carrying afeed dog 14. Said feed bar is end, through whichsaid feed bar is/given its longitudinal or feeding movements. The feedbar is given its rise and fall from'the usual eccentric mounted on themain shaft. The rocking frame 15 has an arm 16 rigidly secured thereto,and said arm is pivotally pivoted to the rocking frame '15, at its rearconnected to an eccentric strap 17 by aball I stud connection 18, asclearly shown in Figs. 3, 5 and 6. Said eccen'tricstrap 17 surrounds aneccentric 19 adjustably se cured to a supporting plate 20. Said-eccen-"trio 19 is provided with a dove tail portion 21, which engagesacooperating dove tail projection carried .by the support 20. The

support 20 is rigidly secured -to the 'main by a set screw 22,.as shownin shaft 21 Fig. 6. Thls support 20 is provided with I outwardlyextending which is passed a bolt portion 25 secured thereto between theears 23, 23, whereby the bolt 24 is held in said ears, so that the samesaid-bolt is ears 23, 23, through prevented from longitudinal .movementthrough said ears. The enlarged --portion 25 preferably has its sidesslabbed, whereby the vsameimay be engaged by a wrench. The bolt 24 isprovided with right .and left hand threads at its opposite ends.

' The eccentric 19 is providedwith av perforated lug 26, which isthreaded for engage ment with the bolt 24 24 having an enlarged may berotated, but

' hanging arm 29, carrying at the forward eccentric 19 is slotted as at27, (see Fig.

' shaft.

rollers with circumferential grooves 41, 42,

- of sufficient depth so that when no material My improved pullerconsists of a bed plate plate .28, from which rises an overend thereof ahead 30, in which reciprocates a rod 31, carrying at the lower endthereof one member of the feeding mechanism of my improvedpuller. Thebed plate 28 of the puller is provided with suitable supporting brackets32, 32 (seerFigs. l and 3). On said brackets is the cloth plate orwork-support 33. The supporting brackets 32are of such height that whensaid puller is mounted on a common base 34 (see Fig. 2) with a sewingmachine, the cloth plate 3.3 of the puller is in the same plane withthecloth plate 11 of the sewing machine, so that material operated upon bythe sewing machine may be passed directly from one cloth plate onto theother.

Passing through the brackets 32 is a shaft 35 which carries at itsforward end a feed wheel 36, which cofiperates with a feed wheel 37rotatably mounted in the yoke 38 secured to the lower end of the bar 31,as shown in Fig. 1 of the drawing. The feed rollers 36' and 37 asclearly shown in Figs. 1 and 2, are provided w'th-projecting ribs orteeth 39 and 40, respectively, which are so shaped and spaced that oneintermeshes with the other. I have also provided my feed which arespacedthe same distance apart as 'the needles of the sewing machine, sothat stitches formed by the stitch-forming mechanism of the sewingmachine will pass through said grooves and all liability of crushing ordestroying the stitch in. any way, is avoided. The grooves, however, are

is. passing between the rollers but the machines are chaining from onestitched article to another, the chain of stitches will be engaged by.the feeding rolls and fed along,

' although said chain of stitches should lie in the grooves.

In order to intermittently rotate the feed wheel 36, I have provided theshaft 35 with a suitable clutch mechanism, which is operated from aneccentric carried by the main shaft of the sewing machine. Said clutchmechanism consists of a collar 43 (see Fig. 7 secured to the main shaft35 by means of a set screw 44. Said collar is provided with an enlargedbore 45 in one end thereof, into which fits a sleeve 46, loosely mountedon the shaft 35. Saidcollar is also provided with cam-shaped recesses 47(see Figs. 5 and 7), in which are located small rollers 48, 48. A spring49 is seated in said recess, and normally. forces the roller up the camsurface of the recess into gripping contact with the sleeve 46. Saidsleeve 46 has rigidly secured thereto an arm 50. When said arm 50 isvibrated in the direction of the arrow shown in Fig. 5, the sleeve 46through the rollers 48 grips the cam face of the recesses in the collar43, and turns said collar, thereby imparting a movement to the mainshaft 35. When, however, the sleeve 50 is vibrated in the oppositedirection, the rollers 48 are moved out of gripping contact with thecollar, 43 and the sleeve is moved relative to the main shaft.

In order to provide a means for holding the main shaft from backwardmovement when the arm 50 is vibrated in the direction opposite from thatshown by the arrow in Fig. 5, I have provided a bracket 51, which issecured to the bed plate of the puller 28 by suitable screws, and at itsupper end is secured to a collar 52, which is loosely mounted on themain shaft, and which is also provided with an enlarged bore or recess53, (see Fig. 7 which receives a reduced portion of the sleeve 43. Saidcollar 52 is provided with recesses 54, 54, having cam faces similar to*the recesses formed in the collar 43, but oppositely disposed relativethereto. Said recesses 54 are each provided with a roller 55 and with aspring seated in said recess 54, and engaging said roller, whereby thesame is normally held in gripping contact with the sleeve 43.

The manner of operating my clutch will be obvious 'from the abovedescription. As the arm 50 is vibrated in the direction of the arrow inFig. 5, the sleeve 46 will grip the collar 43 through the grippingrollers 48, and turn the main shaft to the extent to which the arm 50 isvibrated when the arm 50 is moved in the opposite direction. Thegripping rollers 55 will .;clutcl1 the sleeve 43, and prevent .the mainshaft from rotating in a backward direction. By

this form of vibrating clutch and locking clutch, I have provided aclutch mechanism,

whereby small increments of movement may 56 to an eccentric 57, mountedon the main shaft 21 of the sewing machine. Said eccentric 57 isprovided with a portion having mettle a dove tail recess 58, whichengages a cooperating dove tailed projection 59, mounted on the support20, above referred to.

given to the main shaft of the puller, is varied. As above noted, thebolt 24 is provided with right and left hand threads and the eccentrics57 and 19 are disposed upon opposite sides of the center of the mainshaft, as clearly shown in Fig. 5. By turning the bolt 24, therefore,the eccentrics will be simultaneously moved toward or from the center ofthe main shaft and the throw of said eccentrics will, therefore, besimultaneously adjusted. If the eccentrics are timed so that the throwof each eccentric causes anequal movement of the sewing machine feed andthe feed of the .puller, for any given length of feed, when said lengthof feed is adjusted by moving one eccentric away from thecenter of themain shaft or toward the same, the other eccentric will be similarlymoved, and a similar adjustment would be made in the movements of thepuller feed. By this arrangement of parts the two feeds may be set tomove in unison and whenever the feed of" the sewing machine is alteredto lengthen the stitch, the feed of the [puller will be correspondinglyaltered, and the feeds will still move in unison. Suitable check nuts60* and 60 are provided, to hold the eccentrics in their adjustedposition.

The feed roller 37 is held in engagement with the material by a'fiatspring'61, mounted in the overhanging arm of the puller, and

having one end thereof resting on a lug 62 while the other end thereofengages the collar 63 on the, rod 31. The screw 64 en:

gages. the spring between its ends and by ad ustingsaid screw thetension of the spring may be increased or decreased, and

the pressure of the feed roller 37 on the material correspondinglyvaried :As a means for lifting the feed roller ,37 from the-material, Ihave provided a lever 65, pivoted at 66 to the overhanging arm 29. Theforward endof said lever engages alstud 67 secured .to the rod 31, whilethe other end of said lever .is provided .with an eye 68, which isengaged by a suitable chain or other flexible connection 69.. As shownin Fig. 2, the-flexible connection or chain 69 and the chain 10, arejoined together and connected by a single chain "to a knee lever or foottreadle, so that the presser bar of the j sewing machine and the feed 37of the puller may be simultaneously lifted from the material wheneverdesired. The lever.

' ters Patent, is:

is held by means of a spring 70, normally in contact with the lug 71 onthe head of the machine. i

The operation of my device will be obvious from the above description.The puller is attached to a sewing machine or any other machine'in whichit is desired to I assist the feed thereof.v The material after passingthrough the machine, is passed to the puller between the feed rollersthereof, and as the feed of the main machine opcrates the feed of thepuller will be operated in unison, and the material pulled through themachine. If desired, the stroke of the puller feed may be so adjusted asto be slightly in excess of thatuof the feed of the main machine andthereby the material put under slight strain.

It will be obvious that instead of operating the puller from aneccentric on the main shaft said puller may be operated from the rockingframe of thefeed dog or from any other suitable mechanism, whereby thesame may. be moved in unison with the feed dog of the machine. If saidpuller were operated from the rocking frame of thefeed dog, then alladjustments of the feed dog whereby the stroke of the feed is varied,would produce a like variation in the feeding of the puller, so that thefeed of the puller and the feed of the main machine will be kept inunison for various lengthsof feed movements. I

It will be obvious that from certain aspects, my invention is notlimited to rotary feeding wheels, but that any'other form ofintermittent feed may be substituted therefor, the-essential featurebeing that the feed of the puller shall operate in unison with the feedof the sewing machine-for 'all variations in the length of stitch. Whenit is desired to adjust the throw of the puller independently of thefeeding mechanism of the sewing machine, the nut 50 (see Fig. 4), may beloosened,and the connection between the link 56 and the lever 50 movedtoward or from the center of the shaft. 35. The arm 50 is-slotted at 50*to allow of this adjustment.
